nna'rme APPLIANCE.

To all whom it may concern:

Be it known that I, LUTHER D. SMITH, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a. certain new and useful Heating Appliance; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, ref; erence being bad tothe accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relatesto cooking appliances, and particularly to a heating attachment for ranges, but is not restricted to such use as it may be used in any connection for v which it may be adapted or appropriate.

The primary object of my invention is the provision, in combination with the oven of -a range, of a cooker or heating compartment carried by the oven door and inclosing within the oven when the door is closed.

A further object-of my invention-is the provision of means which is automatically operable, upon a closing of the oven door, to close an electric circuit with theheating element or elements carried within the cooker.

Further objects and advantages of the invention will be apparenhfrom the following detailed description.

While the invention, -1n its broader aspect, is capable of .embodiment in numerous forms, a preferred. embodiment thereof is illustrated in the accompanying drawings,

Figure 1 is afronii perspective view, fV-a range embodying the invention with he oven door, which carries the cooker in open position. Fig. 2 1s a fragmentary section of the range through the oven and cooker with the latter in inclosed position within the oven. Fig. 3Iis' an innerside elevation of theoven door," and Fig. 4 is a fragmentary view-of the range showing the top heating element of the cooker in use as a heating element on the range shelf. I

Referring to the drawings, 1 designates a range, which, in the present instance, is of the electric type and which isprovided in.

its base portion with an oven chamber 2 that is'closed by aswinging door 3. Removably mounted'on the inner side of 1 1 9 Specification of Letters latent.

' on the front of the range.

Application filed November 8, 1915. Serial No. 60,349.

' door 3 is a cooker r, which forms an interior cooking chamber o which is preferably pro vided with a top opening'that is closed by a removable lid (3. The walls of the cooking chamber 5 are packed or otherwise suitably formed to insulate them against heat as is customary in fireless cookers The cooker is provided, in the present-instance, at each side thereof adjacent its front edge with a stud 7 that is adapted to rest in anotched bracket 8 on the inner side of the door 3 to removably retain the cooker in engagement with the door. A springca tch-finger 9 is pivoted to the inner side of the door, as at 10, and is provided at its free end with an outwardly projecting nose portion 11 which is adapted to engage over the top front edge of the cooker -1 when in position on the -door and to prevent a removal of the cooker from the door. The catch-finger .9 is released from looking engagement with the/attachment 4 by having its free end sprung inward, and is retained in such inwardly sprung position by a hooked lug 12 onthe into registering electric socket parts 14:, 14

provided in the bottom of the cooker chamber. The sockets 14, 14 ,have electrical con nection with respective electric plug termina'ls or posts 15, 15 which project from the rearside of the cooker and are insulatingly carried thereby. A pair of electric sockets 16 are insulatingly carried by the rear wall of the oven 2- in position for the terminals 15 to enter the'respective sockets when the -cooker .4 inclosed within the oven, as

shown in, Fig. 2. The sockets 16 are suit ably connected to a source of electric'current supply and have a switch disposed in.circuit therewith to permit an opening or closing of the electric circuit, as desired. .The' switch maybe one of the switches 17 shown The cooker is also shown as being :pro-' vided in the cover or lid6 t roof with an electric heating element 18, which element has the two terminal posts' 19, 19 projecting in'e;;posed;position without the top of the cover. When the cooker is in inclosed position within the oven 2 the terminal posts 19,19 are intended to make contact withrespective spring terminal fingers 20,-which are carried at thetop of the oven interiorly V thereof and are disposed in a-common electric circuit, which may be controlled by one of the switches 16.

It is evident from'the above that when the oven door 3 is in closed position and has the cooker 4 mounted thereon, both the heating elements 13 and 18 of the cooker will be in circuit with respective switches and the current maybe t'urnedinto either or both of said elements as maybe desired to heat the cooker compartments. It will, of

I claim as new, and desire to secure Letters Patent, is

1. The combination with means forming a compartment and having a door closing one side thereof, of a cooker carried by the.

7 door and being inclosed within the compartment when the door is closed, an electric heating element in said cooker, and means automatically operable to place said element in an electric circuit when the cooker is moved into the compartment by a closing of said door. I

2. The combination with means forming a compartment having an opening in a side thereof and a door closing said opening, of

' course, be understood that when any artij cles within the cooker have been heated to adesired or predetermined extent the current may be cut ofi from the heating ele-,

ments 13-and 18 and the cooking continued by reason of the retained heat within the cooker, as is well understood in the art.

The cover or-lid 6, when not being used in connection with the cooker,- may be used as a hot plate or heating element on the range, the range for such purposehaving the shelf.

" 21 thereof provided with electric sockets 22, 22 in suitable spaced relation forreceiv ing and making electrical connection with the terminal posts.19, 19 of vthe cover when i the cover is'placed in inverted position over the portion of the shelf 21 in which the sockets 22 are disposed. When in such position the heating. coil of the heating element 18 within the cover is in circuit with I and controlled by a switch 23.

' It is'evident that when desired, the cooker 4: may be removed from the door?) to permit the oven'2 to be used for cooking or heating purposes. An electric heating element 24 is provided at the bottom of the oven 2 for heating the same, or it may be stove art.

heated-in anyother suitable manner, as is well understood in the range or cooking While I have herein shown and described one specific embodiment-of my invention for illustrative purposes, and have disclosed and disdussedin' detail the construction and arrangement incidental to one specific application thereof, it is to be understood that the invention is not limited to the mere 'detail or relative arrangement of the parts but that deviations from the illustrated formor' embodiment of the invention may be made without departing from the spirit of the.

- signed my name 'claims.

Having thus described ,inyinvention, what closing ofthe door.

door is closed, an electric heating element.

carried by said cooker, and means for automatically placing said element in circuit with a source of electric current supply when the cooker is moved into the oven by a 4. The combination with an oven having a door closin a sidethereof, of a cooker carried by'said door for inclosing within the .oven when thefdoor is closed, a heating element. disposed within the cooker and having exposed terminals at one side of the cooker, a second heating element carried by the lid of the cooker and having exposed terminals atthe topof-the lid,'and' circuit closing con tacts carried by said oven interiorly thereof in position to make contact with the terminals of said heating element. when the cooker is inclosed within the oven.

5. In combination, an oven,-a door cles ing a' side of said oven and having notehed brackets on its inner side, a cooker having studs projecting from its ends and supported by said brackets whereby the cooker is carried by the door, and a spring catch-finger carried by the door and normally engaging the cooker to retain its lugs in engagement with .said brackets.-

In testimony whereof, Ifhave' lhereunto to this specification. I 4 ,LUTHER D; SMIT H..
